The LISST-SL (for StreamLine) is a laser diffraction system for measuring sediment properties in freshwater rivers and streams. It is not designed for use in brackish or saltwater environments. The streamlined body is a minimum drag shape. Twin fins below the body orient the LISST-SL facing upstream before insertion. A pitot static tube on ...

The LISST-Infinite instrument is designed for use in hydro-power plants to monitor sediment concentration and size distribution for turbine protection. The instrument is installed near intakes, or near draft tubes. The turbid water pressure is reduced to 5 PSI or less and then piped or pumped to the LISST-Infinite. A clean water ...

LISST-25X marks a generational advance in the measurement of suspended sediment concentrations and size. Unlike all prior sediment or turbidity sensors, optical or acoustic, the LISST-25X maintains its calibration over a 200:1 range of particle sizes. This is the only sensor capable of holding calibration for sediment concentration ...
